Two of our newbies have quite bloody poops today. I read about coccoidosis etc but it's late here and I can't get anything tonight. I have some ACV in the cupboard, but not the organic stuff, and the waterer is only a small one (2 cups capacity). Can anyone advise whether it's worth adding some to the waterer, and if so, how much would it be for such a small waterer? They are eating, drinking, cheeping what seems to be a normal amount for chicks as far as I can tell, and move about quite freely when they're not huddled up in a sleepy pile of feathers.
